Although the beneficial effects of omega-3 fatty acid in reducing the risk of various of human diseases, such as hypertriglyceridemia and nonalcoholic fatty liver disease, have been demonstrated in clinical and pre-clinical studies, the mechanism of its action is poorly understood. several studies has been reported that Dietary supplementation with fish oil induces many changes in plasma TG profile.

Abstract:
The evolutionary conserved insulin and nutrient signaling network regulates growth andmetabolism. Nutrients are directly utilized for growth or stored, mostly as triglycerides. InDrosophila, activation of insulin/nutrient signaling in the fat body (the fly equivalent of liverand adipose tissue), causes an increase in fat stores composed of several small-size lipiddroplets (LDs). Conversely, fasting produces an increase in LD size and a decrease in fatcontents. The TOR kinase and its substrate S6 kinase (S6K) play a central role in this response,and particularly in Drosophila, they have been sh

The shelf seas of the Arctic Ocean receive large amounts of this terrestrial OC from Eurasian Arctic rivers and from coastal erosion.
